'In the dispensing art and especially that dealing with gasoline and lubricants, it has frequently been the practice of unscrupulous agents to fill acontainer'branded by a certain particular company with a-.difierent.andusuallyinferior quality.of material. Aparticular producing company will, with great effort and expense, produce a certain product and by its own merits and by its advertising, become well known to the user public who will oftimes drive out of their way to procure the product of that company. But due to the .fact that a cheaper or differentproduct is more easily obtainable the dealer or dispensing agent will foist this other product on his custo- Inc-rs, who,.not knowingthe details of filling of the agents reservoir With something that may be just as good but in reality is different, is unfortunately the victim of the fraud.

Besides the consumer who does not get what hepays for,'the concern producing the gradeand quality of material that has been asked for by the unsuspecting public, in having its containers filled withadifierent substitute product and offered. as its own :is also subject to fraud because it loses the .profitsirom the sale of its own gasoline or lubricant, andit also loses that most important thing goodwill, because the inferior product is unsatisfactory to the man who wantsand pays for adefinite article .but who is delivered a substitute.

So far, the means of sealing containers similar to .un'dergroundgasoline tanks and the portable oil tanksincornmon use. around the filling or dispensing station have proved inadequataunsatisfactory and of little practical value and it is therefore, the subject of our invention to producea container which is non-fillable unlessthe proper authorized equipment is used as will be more .fully explained in the following detailed description.

Fig. 1 shows a container of any desired shape orlocation in which it is desiredto retain. a fluid temporarily and-into which the fiuid is .pumped or drained by the action of gravity in large quantities and from which this fluid is removed inrelatively smaller quantities. .In this embodiment chosen for illustration, an underground tank 1 contains gasoline 2 which enters in large quantities through the filler pipe 3 from the hose 4 connecting with the filling source usually a tank Wagon or car (not shown).

The filler pipe 3 has a surmounting shoulder portion called the head 5 and the fiher hose 4 has a cooperating nozzle 6, the nozzle 6 being adapted to project into the head 5 to make a fluid tight joint during thefilling operation and further, adapted to be readily removed after the filling -.operation.

The filler pipe 3 leading tothe bottom portion of the tank 1 is made up of two telescoping sleeves or pipes the outer one being 3 and the inner one 3a which is moved relatively to the outer one from a position flush or nearly so with the pipe 3 to a position substantially in contact with the bottom of the tank 1, the object being that in this embodiment of the invention, the inner sleeve 3a being substantially in contact with the bottom of the tank, practically no fluid may be forced therethrough either by a pump or by the action of gravity. When it is desired to fill this receiver rapidly with substantial quantities of liquid it is essential that the inner telescoping sleeve 3a be raised to a position substantially fiush with the pipe 3, thereby allowing a sufi'icient outlet of the liquid.

The upper portion of the sleeve 30. is integrally attached to a collar or cylinder 7 whose shoulder, resting on the sleeve 3, limits the lowermost position. As shown in Figs. 3 and 4, the collar 7 is provided with a cylinder locking means 8 of any approved or desired type and the nozzle 6 of the filler hose is provided with a raised key portion 9 which cooperates with the tumblers 10 of the lock 8 so that when the nozzle 6 is projected into the collar '7, the proper nozzle being used, the tumblers 10 are properly positioned to allow a rotation of the collar, through a rotation of the hose 4, nozzle 6 and the cooperating pin and slot connection 611.

The head 5 on the outer pipe 3 is provided with a pin 11 inwardly projecting into a depressed carn slot or groove 12 in the collar '7, the arrangement being such that a partial rotation of the collar 7 will force the cam portion along the pin on the relatively fixed outer sleeve and thereby raise or lower the inner sleeve Ed depending upon its initial position.

The operation of this device is therefore, obvious. When it is desired to fill the tank with a liquid from an authorized source and conveyed through a hose with a particular key nozzle, the nozzle is projected into the filler cap, unlocking the cooperating key tumblers, the nozzle then being givena partial turn, raising the inner sleeve and thus allowing the liquid to pass into the tank.

On the other hand, if the fiuid to be placed into the tank has not been placed in a container such as a tank wagon or car, with the authorized discharge hose and the unlocking key nozzle, the nozzle cannot unlock the collar on the inner sleeve and cannot therefore, raise this sleeve from its position relatively close to the bottom of the tank and the liquid will, at best, flow so slowly as to invite suspicion and detection, and

practically prevent filling.

To prevent removal of the nozzle before the tank has been effectively closed again, the lowermost projection 9a on the key of the nozzle projects below and beyond the lowermost tumbler 10a and securely holds the nozzle in position in the filler pipe as long as the inner filler sleeve is raised or in filling position. The tank must be closed before the filling hose can be removed.

The filler pipe 3 and the inner tube 3a allow suificient liquid to fiow into the pipe from the reservoir so that a gage stick may be inserted through the open top to determine the depth of liquid therein.

In Figures '7 to 12 we have shown another embodiment which our invention may take and in which the filler pipe 3', integrally fastened head 5 and nozzle 6 are similar to the corresponding parts shown in Figures 1 to 6. It will be noted however, that there is no inner sleeve here but that the filler pipe is sealed by a different valve means comprising two semi-circular doors 20, hinged at 21 to a rotatable internal hollow collar or cylinder 22. The doors have a projecting ear portion 23 extending from the hinged portion and at a substantial right angle thereto, this car cooperating with a cam shaped surface 24 on the head 5. As shown in Fig. 12, a, b, and 0, each shows a different step in the cam surface and the relation of the position of the valve doors. Fig. 7 shows one extreme position and Fig. 8 the other.

These valve doors are, as has been explained, hinged on the rotatable collar 22, and the projecting ear portions cooperate with the cam portion on the relatively fixed head 5. To open or close the doors therefore, it is only necessary to rotate the collar. 22 within the head 5 and thus effect the pivoting of the doors to change their position.

. In order to rotate this inner collar 22, the projecting key portion 9 on the nozzle 6 must properly displace the cooperating tumblers 10' in the cylinder look after which, the collar 22 is free to rotate, being guided by the pin 11 projecting from the head 5' into the depressed slot portion 12 in the head 22. This slot has a plane surface inasmuch as there is no upward movement necessary. The screw cap 25, fitting over the head of the nozzle is used in this modification to retain the nozzle 6 on the filler pipe head 5'. To additionally secure the doors 20 in the closed position, two diametrically opposite projecting ledges 26 and 2'7 have been provided. They are so placed that during the normally closed position as determined by the cam 24, the ledges will extend under the unsupported edges of the doors and firmly hold them. When the collar 22 is ro-' tated, the ledges 26 and 27 do not interfere with their complete opening to allow filling of the receptacle.

The filler pipe 3, is commonly adapted for such curb installations as desired, but in such curb installations, the lowermost part of the filler pipe drains away from the filler pipe to the reservoir. It is therefore, impossible to gage the quantity of fluid in the reservoir as the true level is not in a straight portion of the pipe, and hence, means to allow opening of the valve doors for gaging purposes is unnecessary.

Whereas we have described our invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention and we do not, therefore, desire to limit ourselves to the specific embodiments shown but to interpret the invention broadly within the scope of the appended claims.
